Description

Technical Field

[0001] This invention relates to the field of sodium fluorosilicate wastewater treatment technology, specifically to a device for treating suspended solids in sodium fluorosilicate production wastewater. Background Technology

[0002] Sodium fluorosilicate is an important chemical raw material widely used in the production of glass and ceramics. Due to the special nature of its production process, a large amount of wastewater containing suspended solids is generated during the production of sodium fluorosilicate. Sodium fluorosilicate production wastewater contains various suspended solids, including silica gel, calcium fluoride, and calcium phosphate. If this wastewater is not effectively treated and purified, it will cause serious pollution to the environment.

[0003] Existing sodium fluorosilicate production wastewater suspended solids treatment devices mostly employ sedimentation methods, adding flocculants to the wastewater to settle suspended solids. However, conventional methods cannot effectively and evenly mix the flocculants into the wastewater, resulting in slow sedimentation efficiency and insufficient settling of suspended solids, thus causing low treatment efficiency in existing devices.

[0004] Therefore, this invention introduces a device for treating suspended solids in sodium fluorosilicate production wastewater. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a device for treating suspended solids in sodium fluorosilicate production wastewater. This device has the advantage of being able to add flocculants to the sodium fluorosilicate production wastewater while simultaneously stirring it, thereby enabling the suspended solids in the wastewater to settle rapidly, thus solving the problems mentioned in the background technology.

[0007] Preferably, a fixed shaft is fixedly connected to the top of the treatment tank, and a spur gear II is coaxially rotatably connected to one end of the fixed shaft. An upper ratchet plate is fixedly connected to the bottom of the spur gear II. The upper ratchet plate meshes with a lower ratchet plate, and the lower ratchet plate is slidably connected to the fixed shaft. A connecting spring is fixedly connected to the bottom of the lower ratchet plate, and one end of the connecting spring is fixedly connected to the treatment tank. A pressing plate is fixedly connected to the lower ratchet plate, and a pressing airbag is provided at the bottom of the pressing plate, with one end of the pressing airbag penetrating through the top of the treatment tank.

[0008] Preferably, the fixed sleeve shaft is rotatably connected to a threaded rod, the threaded rod passes through the lifting sleeve shaft and is threadedly connected to the lifting sleeve shaft, the lifting sleeve shaft is rotatably connected to a connecting arm, and one end of the connecting arm is rotatably connected to a scraper.

[0009] Preferably, a rotating motor is provided on the top of the processing tank, and a spur gear four is coaxially and fixedly connected to one end of the output shaft of the rotating motor four. The spur gear four meshes with the spur gear one, and the spur gear one is coaxially and fixedly connected to one end of the rotating sleeve shaft one.

[0010] Preferably, the other end of the rotating sleeve shaft is coaxially fixedly connected to a bevel gear, the bevel gear meshes with a bevel gear, the bevel gear is coaxially rotatably connected to a connecting shaft, and one end of the connecting shaft is fixedly connected to the fixed sleeve shaft. The bevel gear meshes with a bevel gear, and the bevel gear is coaxially fixedly connected to one end of the rotating sleeve shaft.

[0011] Preferably, the output shaft of the rotating motor is coaxially fixedly connected to a spur gear three, which meshes with a spur gear two.

[0012] Preferably, a rotating motor 2 is fixedly installed on the top of the processing tank, and a spur gear 5 is coaxially fixedly connected to the output shaft of the rotating motor 2. The spur gear 5 meshes with a spur gear 6, and the spur gear 6 is coaxially fixedly connected to one end of a threaded rod.

[0013] Preferably, the number of bevel gears is two.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This sodium fluorosilicate production wastewater suspended solids treatment device, through the setting of the stirring assembly, in use, the rotation of the output shaft of the rotating motor drives the spur gear four, which is coaxially fixed to its end, to rotate. This controls the rotation of the spur gear one meshing with it and the rotating sleeve shaft one, which is coaxially fixed to the spur gear. In turn, the stirring rod one, which is fixed to the outer surface of the rotating sleeve shaft one, stirs the wastewater stored inside the treatment tank. During the rotation of the rotating sleeve shaft one, it drives the bevel gear one at its other end to rotate, thereby controlling the rotation of the bevel gear two meshing with it. This controls the rotation of the bevel gear three meshing with the bevel gear two and the rotating sleeve shaft two, which is coaxially fixed to the bevel gear three, to rotate in the opposite direction to the rotating sleeve shaft one. This allows the stirring rod one and the stirring rod two to rotate and stir in both directions.

[0016] 2. This sodium fluorosilicate production wastewater suspended solids treatment device, through the setting of the pressing component, when the output shaft of the rotating motor one rotates, it will drive the spur gear three to rotate, thereby controlling the rotation of the spur gear two meshing with it. During the rotation of the spur gear two, it will drive the upper ratchet disk fixedly connected to its bottom to rotate as well. This causes the rotating upper ratchet disk to squeeze the lower ratchet disk meshing with it. Under the action of the connecting spring connected to the bottom of the lower ratchet disk, the lower ratchet disk will reciprocate up and down along the trajectory of the fixed shaft. This controls the pressing plate connected to the lower ratchet disk to intermittently press the pressing airbag, thereby pumping the flocculant stored inside the pressing airbag into the treatment tank.

[0017] 3. This sodium fluorosilicate production wastewater suspended solids treatment device, through the setting of a scraping mechanism, allows the suspended solids in the wastewater inside the treatment tank to settle during operation. The wastewater is then discharged through the drain pipe at the bottom of the tank. The rotation of the output shaft of the rotating motor drives the coaxially fixed spur gear five to rotate. This spur gear five, in turn, drives the meshing spur gear six and its coaxially fixedly connected threaded rod to rotate. This controls the downward movement of the lifting sleeve shaft, which is threadedly connected to the threaded rod. When the lifting sleeve shaft descends to a certain extent, the bottom of the scraper contacts the inner bottom of the treatment tank. The lifting sleeve shaft continues to move downward, increasing the pressure between the bottom of the scraper and the inner bottom of the tank. This causes the bottom of the scraper to deform, expanding to both sides. Under the action of the connecting arm, the scraper expands outward, thus scraping the suspended solids deposited at the bottom of the treatment tank, facilitating subsequent cleaning with water flow.

The lower ratchet disc 16 is fixedly connected to a pressing plate 17. The bottom of the pressing plate 17 is provided with a pressing airbag 18, and one end of the pressing airbag 18 penetrates through the top of the processing tank 2. The connecting spring 29 can provide a certain buffer when the lower ratchet disc 16 is disengaged from the upper ratchet disc 15 to prevent damage to the equipment due to sudden stop.

[0029] The air bladder 18 itself is resilient and will reset after being pressed, and will draw in air to ensure stable internal pressure so that the flocculant can continue to be pumped out when pressed again.

[0030] Among them, the fixed sleeve shaft 3 is rotatably connected to the threaded rod 19, the threaded rod 19 passes through the lifting sleeve shaft 20 and is threadedly connected to the lifting sleeve shaft 20, the lifting sleeve shaft 20 is rotatably connected to the connecting arm 21, one end of the connecting arm 21 is rotatably connected to the scraper 22, the scraper 22 has deformation and expansion capabilities, and can effectively adapt to the inner bottom of the treatment tank.

[0031] Among them, the scraper 22 is made of rubber, which gives it good deformation ability and strong wear resistance.

[0032] Among them, the top of the processing tank 2 is equipped with a rotating motor 23, and one end of the output shaft of the rotating motor 23 is coaxially fixedly connected to a spur gear 4 25. The spur gear 4 25 meshes with a spur gear 5, and the spur gear 5 is coaxially fixedly connected to one end of the rotating sleeve shaft 4.

[0033] Among them, the other end of the rotating sleeve shaft 14 is coaxially fixedly connected to the bevel gear 17, the bevel gear 17 meshes with the bevel gear 29, the bevel gear 29 is coaxially rotatably connected to the connecting shaft 8, and one end of the connecting shaft 8 is fixedly connected to the fixed sleeve shaft 3. The bevel gear 29 meshes with the bevel gear 312, and the bevel gear 312 is coaxially fixedly connected to one end of the rotating sleeve shaft 210.

[0034] Among them, the output shaft of the rotating motor 23 is coaxially fixedly connected to the spur gear 24, which meshes with the spur gear 14.

[0035] Among them, a rotating motor 26 is fixedly installed on the top of the processing tank 2. The output shaft of the rotating motor 26 is coaxially fixedly connected to a spur gear 5 27. The spur gear 5 27 meshes with a spur gear 6 28. The spur gear 6 28 is coaxially fixedly connected to one end of the threaded rod 19.

[0036] Among them, the number of bevel gears 29 is two.

[0037] Working principle: During use, sodium fluorosilicate production wastewater is first injected into the treatment tank 2 through the water injection pipe on the side. Then, the rotation of the output shaft of the rotating motor 23 drives the spur gear 25, which is coaxially fixed to its end, to rotate. This controls the rotation of the spur gear 5 meshing with it and the rotating sleeve shaft 4, which is coaxially fixed to it. This causes the stirring rod 6, which is fixed to the outer surface of the rotating sleeve shaft 4, to stir the wastewater stored inside the bracket 1. During the rotation of the rotating sleeve shaft 4, the bevel gear 7 at its other end will rotate, thereby controlling the rotation of the bevel gear 9 meshing with it. This controls the rotation of the bevel gear 12 meshing with the bevel gear 12 and the rotating sleeve shaft 10, which is coaxially fixed to the bevel gear 12, to rotate in the opposite direction to the rotating sleeve shaft 4. This causes the stirring rod 6 and the stirring rod 11 to stir the wastewater inside the tank. The sodium fluorosilicate production wastewater is subjected to bidirectional rotary agitation. Simultaneously, as the output shaft of the rotating motor 23 rotates, it drives the spur gear 24 to rotate as well, thereby controlling the rotation of the meshing spur gear 14. During the rotation of the spur gear 14, it drives the upper ratchet disc 15 fixedly connected to its bottom to rotate as well. This causes the rotating upper ratchet disc 15 to squeeze the meshing lower ratchet disc 16. Under the action of the connecting spring 29 connected to the bottom of the lower ratchet disc 16, the lower ratchet disc 16 will reciprocate up and down along the trajectory of the fixed shaft 13. This controls the pressing plate 17 connected to the lower ratchet disc 16 to intermittently press the pressing airbag 18, thereby pumping the flocculant stored inside the pressing airbag 18 into the interior of the bracket 1. This improves the thorough mixing of the sodium fluorosilicate production wastewater and the flocculant, and allows the suspended solids inside to settle rapidly.

[0038] Finally, after the suspended solids in the wastewater settle, the wastewater is discharged through the drain pipe at the bottom of the treatment tank 2. Then, the rotation of the output shaft of the rotating motor 26 drives the spur gear 5 27, which is fixedly connected to it on the same axis, to rotate. In turn, the spur gear 5 27 drives the spur gear 6 28, which meshes with it, and the threaded rod 19, which is fixedly connected to the spur gear 6 28 on the same axis, to rotate. This controls the lifting sleeve shaft 20, which is threadedly connected to the threaded rod 19, to move downward. When the lifting sleeve shaft 20 descends to a certain extent, the bottom of the scraper 22 will contact the inner bottom of the treatment tank 2. Then, the lifting sleeve shaft 20 will continue to move downward, increasing the pressure between the bottom of the scraper 22 and the inner bottom of the treatment tank 2. This causes the bottom of the scraper 22 to deform and expand to both sides. Under the action of the connecting arm 21, the scraper 22 expands outward, thereby scraping the suspended solids deposited at the bottom of the treatment tank 2. This makes it easier to clean them later by water flow impact, and the settled solids are placed on the inner bottom of the treatment tank 2.
